M20-7870246P

Overview

The Harwin M20-7870246P is a dual-in-line socket assembly featuring 4 positions arranged in a 2x2 configuration. It utilizes a 2.54 mm (0.100 inch) pitch and is designed for surface-mount technology with bottom entry termination. The connector employs push-pull locking mechanisms and accepts male pins with tin plating. Constructed from PA6T insulation, it supports a current rating of 3A per contact and operates within a temperature range of -40°C to 105°C.

Feature Summary

• Surface-mount dual-in-line socket design with bottom entry orientation
• Push-pull locking mechanism for secure mating engagement
• PA6T insulation material ensuring UL94 V-0 flammability rating

Applications

• Board-to-board interconnects requiring low-profile mounting
• Automotive electronic control unit connections
• Industrial instrumentation signal routing

Procurement Notes

Verify the specific suffix 'P' against official Harwin documentation to confirm if it denotes pick-and-place compatibility or a distinct variant, as suffixes may alter mechanical or electrical characteristics. Cross-reference the part number with the latest M20 catalog to ensure availability status and confirm that the tin-plated contacts meet the required environmental specifications for the intended application environment.

Selection Notes

Select this component when a compact, surface-mounted dual-row interface is required for low-current signal transmission. Ensure the mating header matches the 2.54 mm pitch and compatible pin length. Consider the push-pull retention requirement versus standard press-fit alternatives. Verify that the PCB footprint accommodates the specific SMT termination geometry and that the operating temperature range aligns with system thermal profiles.

Part Context

This part belongs to the Harwin M20 series, a widely used rectangular connector family known for high-density interconnect solutions. The M20 line offers various configurations including headers, sockets, and wire housings in both through-hole and surface-mount formats. This specific model represents a small-form-factor socket optimized for automated assembly processes in space-constrained electronic assemblies.

Replacement Considerations

Compatible substitutes include other Harwin M20 series dual-in-line sockets with matching 2x2 positioning and SMT termination, such as M20-7870246 variants. Ensure any replacement maintains the same 2.54 mm pitch, push-pull locking style, and PA6T insulation material to preserve mechanical fit and thermal performance.
